Police have revealed that convicted serial stabber Yishai Schlissel, who murdered one person and wounded several others in during last year's Jerusalem Pride Parade, was arrested on suspicion of attempting to coordinate an attack on this year's parade.

Haredi extremist Schlissel is currently serving a life term for the murder of Shira Banki at the 2015 parade. Police say he made contact with people outside the prison where he is being held in preparation for an attack.

Specifically, police intelligence indicates he enlisted his brother Michael - who is currently in police custody - to carry out an attack and disrupt the march, which is set to take place today.

Yishai Schlissel was arrest in his cell yesterday (Wednesday), and was brought in for questioning in Jerusalem. Today he will appear before Jerusalem District Court to respond to a police request to hold him in their custody until Sunday.

His brother Michael was also arrested on Wednesday, and his detention was extended until today. Other family members were also arrested, and are still under investigation despite having been soon released with some conditions - including a police restraining order banning them from the area of the gay march.

Jerusalem District Police Commander Yoram Halevi outlined the ongoing police investigation in a statement:

"We thwarted and prevented intentions to harm human life during the course of the parade itself. The parade will take place as planned without any changes. It is our intention to enable the general public to exercise their freedom of expression and protest, as part of the democratic character of the State of Israel."
